SCRAPER Fon Fie-'annees on OTHER Disks.

Specification of Letters Patent.

. Patented Oct. 2, 1905.'

Application filed October 18, 1905. Serial No. 283,284.

the ollowing is a specification.

This invention relates to Scrapers. One object is to provide an exceedingly simple, inexpensive, durable, and efficient scraper.

Another object resides in the provision of a combined fender -of the disk variety and a scraper therefor.

A further object of the invention is to provide a scraper for disks of various types so mounted as to lie normally out of contact with the disk and to eneage the same automatically to relieve it ofioreign matter.

It is still further desired to construct a fender of the nature stated whereby it may be quickly attached to or detached from4 a beam of a cultivator, its disposition be preferably slightly in advance oi the `inslildczye shovel to cperate upon the surface-soil to any desire depth and prevent the surface soil, weeds, clods, or other foreign matter being thrown toward the rows of corn or the like While the said inside shovel is throwing subsoil toward the row.

With these and other objects in view the hereinafter more fully described, shown in.

the accompan fr drawings, and particulai-ly pointed oiitnlin the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made Within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective view of my invention connected with the beam of a cultivator. Fig. 2 is a transverse sectional view onrthe line 2 2 of Fig. 1. Fig. 3 is a detail view of a clamping member similar to the 'clamping member shown in Figs. 1 and 2, but designed for engagement with a beam-to reverse the disposition of the fender with respect to the cultivator. Fi 4 is a detail view of thehub-engaging colar of the fender providedy .with op ositely-disposed shoulders, andl Fig-5 is a etail view of the cleaningelernnt. f1

Referring now more particularly to the a0- companying drawings, the reference characf: ter 1 designates a portion of-a beam, and 2.a; shovel connected up with the vbeam ill-thee I `6o.,4 is in the form of av concavo-conveX-shaped rotatabledisk 3, prousual manner My improved fender vided with a hub 4, whereby it may be mounted for rotation upon the lowerfhorizontal end 5 of a hanger 6, which latter is se.

cured to the beam in the manner hereinafter explained. zontal portion 5 of the hanger 6 arecollai's 7 and 8, each havin 1r a recess 9 formedabout its central bore and in the correspon face,-

Slidably disposed uponthe horito receive the respective ends of the hu 4 of the disk-fender 3, there being a suitable washer 10 disposed between the corresponding end of the hub 4 and the bottom of the corresponding recess'Q of the collars 7 and 8.`

By reason of the fact that the inner face of the collar 7 is disposed adjacent the upright portion ofthe hanger 6 and the fact that the collar 8 is provided with a set-screw 11 it is .obvious that the hub 4 of the disk fender may be so disposed with respect to the collar 7 and 8 as to prevent it becoming accidenf tally disengaged from its axis 5. If preferred,A

a set-screw 12 may be asociated with the collar 7 for engagement with the axle 5, so that the disk fender may be adjusted longitlidi nally of the axle 5 oi the hanger 6.

It will be.

understood that the ends ofthe hub 4 are en-v i gaged loosely in the corresponding recess ofithe collars 7 and 8 to permIt of free rotation ofthe disk fender 3.

In order to secure the hanger "6A to -beam 1 slightly inadvance of the shovel 2,1

provide a clamping-block 13, havingonef-flat I side 14 for engagement with the corresponding side of the beam 1, and` alsoprovided.l

with a bore 15 -for the receptionoi the hanger 1 6. The hanger 6 may be adjusted vertically", in the bore 15 of the clamping-block. 1.3 by f means of a suitable set screw 16, andgit will be observed that the up er end-of fthe'l` clampingblock 13 is provi Ied with a ra;v-` dially-directed fla o'e 17 for engagement Iwith the upper lface of t l ebeam 1. ing-block 13 1s provided with ani upper car This clamp.-

18 and a lowerfearlQ, the said ears being.." arranged upon opposite sides of the clamp ying-block. The ear 13 includes a'portionofg the radially-directed flange 17, and through .I

IIO

the same 1s formed a short horizontal slot 20, there being a slot 21 formed through the ear 19 downwardly and upon an incline, as shown. These slots 20 and 21 of the respective ears are designed to receive the oppositel -dis osed legs 22 of the'U-shaped key 23, W lose ight portion 24 extends upon the' opposite si e of the beam from that upon which the clamping-'block 13 is disposed. The free extremities of the legs 22 'may be screw-threaded for the reception` (if suitable nuts 25. This key 23 may be termed a clamping member for coperatio'n with the clam in member 13, and by reason of the detac ab e engagement of the clamping member 23 with respect to the clamping-block 13, or, vice versa, it is obvious that the clam ing members, together with the fender itseif, may be readily laced upon or removed from the beam 1. is obvious also that the clalnpin members. 13 and 23, and consequently the ender, may be adjusted lon itudinally of the beam 1 to present the dis fender at different distances toward or away from the shovel 2. While dwelling 2 5 `upon this feature of the invention, it might be remarked thatthe clampingdolock 13 may be reversed in form, as shown in Fig. 3, for disposition upon the opposite side of the beam 1,-whereby the device is ada ted for right or left use with respect to the cu tivator.

From the foregoing it. will be' understood ,that the disk fender 3-is rotatable upon its axle and that it may be adjusted vertically with respect to the eam 1 by reason ofthe vertical adjustment provided for the hanger 6 through the instrumentality of the setscrew 16. Since the hanger 6 is circular in section, corresponding to the bore 15 of the clamping member 13, it is obvious that the hanger 6 may be revolved therein to present the disk fender 3 at various angles with respect to the plane of the beam 1 or the shovel 2, so as to re ulate not only the line of travel lof the disk onder, but also the quantity of weeds, surface-soil, and other foreign matter to be thrown toward the shovel and not toward therows. v

I provide means for automatically cleaning the disk fender. This automatic means consists of a scraper 26, whose rear edge 27 is enlarged and provided with a bore 28, circular in cross-section, whereby the scraper may be mounted for lateral movement upon a bolt 29, which is removably fitted in the recess 30 in the top of the aforesaid collar 7. This recess 30 is disposed between two shoulders 31 and 32 forA a purpose presently explained. The bolt 29 is provided with a head 33 at its upper outer end to prevent accidental disenagement of the scraper 26 from the bolt. s shown in the drawings, the bolt 29, and consequently the scraper 26, is normally out y of .contact with the disk 3, lyingiagainst the inclined face 35 of the shoulder 31. whereby it cannot move a great distancvn from?. the

disk. When the disk is free of iereign matter, the scraper 26 does not engage therewith; but in the event foreign matter should cling to the concaved face of the disk 3 it would f engage the beveled edge 34 of the scraper 26 and throw the latter into engagement with the disk, thereby relieving the lattaA of such foreign matter. The shoulder 32 is provided for the same purpose as the shoulder 31; but the shoulder 32 does not coperate with the shoulder 31, the shoulder 32 bein designed l particularly for coperation with t ie scraper 26 when the fender is changed for operation l from the right to the left side, or vice versa. I t will thus be seen that my improved clean` ing element 26 o crates autoniatically to relieve the disk shield or fender of any foreign matter that may cling toits concave face.

In the use of my invention the surface-soil,

weeds, and the like are operated upon prior to the subsoil. IIence the disk-sha ed fen* der or shield 3 throws the surface-soi Weeds, &c. ,away from the row, while the cultivatorshovel follows immediately thereafter and throws the subsoil toward the row. This is ene of the main objects of the invention, and
